Immersion Tin PCB is lead Free type

Immersion Tin is the lead-free alternative to the Hot Air Leveling(Hasl) process on pcbs.
So if you project is require RoHS complance,Immersion Tin Surface Finish PCB is your choose.

The capabilities of Immersion Tin Surface Finish PCB

On printed circuit board surface and the bore holes,the thickness of Tin is between 0.7 μm and 1um.
But about capabilities also depend on every PCB manufacturing factory.
You know the capabilties of China PCB have very difference.

The Function of Immersion Tin

The tin layer protects untreated copper from oxidation; it is a perfect foundation for soldering applications, as well as for plug contacts during the production of Printed circuit Board.

The Use area of Immersion Tin Surface Finish PCB

Within the electronics industry,immersion tin is recognized as a reliable surface finish for both PCBs and IC substrate applications. It is used in many market segments, such as automotive, communications, consumers and industrial electronics.
